Milecastle 1 (Stott's Pow) was a milecastle of the RomanHadrian's Wall. It was located near the (now disappeared) valley of Stott's Pow. Its remains are covered over, and are located beneath the recreation ground at Miller's Dene. Early excavations and investigations of Turret 0B were mistakenly interpreted as Milecastle 1.
1732 - Horsley recorded the milecastle as short-axis and also its proximity to Stott's Pow.
1848 - Collingwood Bruce studied the wall and wrote:
On the top of the rise about 80 yds from the brook (Stott's Pow) is the site of the first milecastle. The ground is under tillage, but its slightly elevated surface, (has a) number of small stones... sprinkled over it...
1852-4 - Henry MacLauchlan surveyed the milecastle's position and recorded it as a short-axis milecastle.
1928 - F G Simpson tested the site and found only Roman occupation soil and debris remained, assuming that even the foundations had been robbed away. Simpson measured from outside edge of the east gate of Segedunum to the centre of Milecastle 1 at 1,443 yards (1,319 m). His measurements between the centres of Milecastle 1 and Milecastle 2 was ed 1,453 yards (1,329 m).
1947 - The recreation ground which now covers the site of Milecastle 1 was leveled in 1947. Part of the "Wall Ditch" and traces of the milecastle were still according to Grace Simpson. She also stated in her notes (circa 1978) that the fragment of Wall Ditch had now completely disappeared but the trace of the milecastle was still faintly discernible.
Each milecastle on Hadrian's Wall had two associated turret structures. These turrets were positioned approximately one-third and two-thirds of a Roman mile to the west of the Milecastle, and would probably have been manned by part of the milecastle's garrison. The turrets associated with Milecastle 1 are known as Turret 1A and Turret 1B.
